[Zope] buildout question
I'm using collective.recipe.patch to patch plone.recipe.zeoserver during a
buildout. The problem is that after applying the patch the py file isn't
consistently reloaded. If I look at the timestamps, I can see that the pyc
file isn't always regenerated after the patch is applied. Is there anyway to
force a reload with buildout? If I run buildout a 2nd time it then runs
fine.
TIA,
- Jim

[Zope] Older Zope w/newer CA packages
We are currently on Zope 2.9.6 and we are working on upgrading but it isn't going to happen anytime soon. I'm trying to use a package that is depending on a few newer component architecture packages; zope.component, zope.interface... Even though zope.component and zope.interface hadn't been egged in 2.9.6, Zope Products seem to import from zope.component in Python lib instead of zope/component in the Zope. Is there any clean way to isolate the newer packages? If its possible this might actually help with a gradual upgrade as well. Any recommendations or techniques would be most useful.

Re: [Zope] using formlib for nonclasic content types
I went through the same motions as you in Zope2.12 trying to use Phillkon's book as a guide. I think I ran into the same problem as you. The key is in the package five.localsitemanager. My Site Interface is nothing. class IMySite(Interface): """My Site"" In my site.py I have the following. ... from five.localsitemanager import make_objectmanager_site ... class MySite(Folder): implements(IMySite) def __init__(self, id): setHooks() Folder.__init__(self, id='Mine') make_objectmanager_site(self) <- key to making a OFS folder a site setSite(self) notify(NewMySiteEvent(self) After that you can treat your MySite OFS Folder like a site. Register utilities with it, setHooks, and setSite.

[Zope] Five EditFrom and Fields appears broken
Does anyone successfully use zope.formlib.form Fields with Products.Five.formlib.formbase EditForm? I was trying to figure out why my form_fields.omit and custom_widget were being ignored. I followed it up the stack and found the method setUpEditWidgets in zope.app.form.utility never takes Fields into account and just looks at the schema and context to determine the fields. So I was starting to think maybe you don't use Fields with Five forms, but there is a unit test in Products.Five.formlib.tests view.py that actually thinks its using Fields. I don't think this is actually the case though, the test just doesn't touch omit or custom_widget functionality so it passes thinking Fields is working. The /Products/Five/form/__init__.py imports zope.app.form.utility setUpEditWidgets. zope.formlib has a different setUpEditWidgets method in zope/formlib/form.py that actually takes form_fields as the 1st param. So in summary, if you think your using Fields in Five try using omit or custom_widget and see if it works and you actually are really using Fields. If it works maybe I have something messed up on my end.

Re: [Zope] Zope2.12
I know of Five but I must admit I'm not that well acquainted with it. On the contrary, I was under the impression that Five was going to be falling out of usefulness as ZTK was being integrated in Z2. Thanks for clearing this up for me.

Re: [Zope] Zope2.12
So far I had just tried developing a site and allow it to be Added and
Viewed in the ZMI.
In the Z2.12 instance/etc/site.zcml I have...
In the browser dir I put a configure.zcml.
ZopeXMLConfigurationError: File
"/home/binbrain/Programs/Zope2.12/instance/lib/python/Test/browser/configure.zcml",
line 14.2
ConfigurationError: ('Unknown directive', u'
http://namespaces.zope.org/browser', u'containerViews')
So containerView is declared in
./zope.app.container-3.8.0-py2.6.egg/zope/app/container/browser/meta.zcml
and I proceeded to just add it etc/site.zcml. That's when I noticed that the
package-includes were by in large missing. At least it looks that way.

Re: [Zope] Zope2.12
Yes, I'm running into missing bits in various places. So even though Z2.12 is based on ZTK eggs, and ZTK eggs are designed using all the CA goodness, I still can't easily develop using those methods. So I'm left leaving this conversation thinking that I'm back to developing Products using the esoteric manage_* methods, even in 2.12.

Re: [Zope] Zope2.12
So developing in Z3 had several perceived benefits no? The problem is that in many cases existing projects couldn't just move to Z3 and start using the CA. From Z3 development was born ZTK, a modular CA implementation that Z2 could now leverage, and I thought in theory all the Z3 CA goodness was now brought to us in Z2 development. I have several existing Z2 Products that aren't going anywhere. Now I want to start developing new stuff using CA paradigms in Z2. This seems like it should now be possible because Z2.12 itself is now built on ZTK. However, I'm running into problems. For example, zcml directives such as the one in zope.app.container-3.8.0-py2.6.egg/zope/app/container/browser/meta.zcml: name="containerViews" aren't wired into Z2.12 it seems.

Re: [Zope] Zope2.12
Perhaps I'm misunderstanding the implications of basing Zope2.12 on ZTK eggs. I was under the impression it would allow sites to be developed in a similar way to how its done in Zope3, ie placing your site in instance/lib/python/ and wiring it all together using the site.zcml now present in the Zope2.12 instance/etc dir. It seems like it should be possible, but maybe not.

[Zope] Zope2.12
I'm trying to wrap my head around what the changes in Zope2.12 can mean for how I develop in Zope2 now. I've developed things in Zope3 and am getting stuck attempting the same methods in Zope2.12. So I see now that etc/ now has a site.zcml. But what is missing is the package-includes directory that provides the wiring to zcml directives in the varies packages. Why are those configurations missing from Zope2.12.2 etc/? I am trying to make it so a site can be added the same it is added in the Web Component Development with Zope 3 book and finding that the browser directives that declare the menu item and container view are missing from the wiring. Overall, it would be helpful for the Zope2.12 documentation to give a better idea about how to develop in the new ZTK way. I'm sure someone is working on it though.

I don't want to have two trunks, two business logics etc. > Hi, Lumir You might take a look at pyjamas (http://pyjs.org). Using pyjamas, you can have common code for business logic and also for the GUI on web and desktop. The main data transfer/persistence mechanism in pyjamas is JSON-RPC, so that part of the model can be zope or anything that can do JSON-RPC. If you like wxPython GUI code, pyjamas code is very similar, and there are examples using PureMVC (http://puremvc.org) in the repository. You cannot, at present, use zope.interface to do automatic widget generation in pyjamas. On the other hand, it is really easy to do custom widgets and client-side display logic. You write your widgets and their behavior in python, not in HTML and javascript. Styling, however, can be done with css. In the eight months since I first experimented with pyjamas (http://www.mail-archive.com/zope@zope.org/msg31618.html), it has improved substantially. Fewer gotchas. More joy.

I'm sure there are more. We and canonical use the Zope Framework. We don't use an application. Zope (aka Zope 2) is an extensible application.

Re: [Zope] Experiment: Pyjamas with Zope
Quick note. I found that The "fix pyjamas" question in my previous note could be handled with a ~100 line python module that makes a new class descending from pyjamas.HTTPRequest.HTTPRequest, but overriding asyncPostImpl with a supported content-type, e.g., "application/json". The module is mostly copy-paste from pyjamas.JSONService and pyjamas.HTTPRequest, but I'll provide it to anyone interested. It was really simple to do.

[Zope] Experiment: Pyjamas with Zope
So, I have a need to put together a more elaborate web page. Lots of pop-up dialog boxes and dynamically-updated choice lists. How to do that? I take a look at Pyjamas http://pyjs.org. Pretty cool. Here's the theory. Write fancy application web page in python using the Pyjamas/GWT API, then "compile" it to javascript. Serve it through zope, which will handle auth/auth. Client-server communication flows through json-rpc calls. What could possibly go wrong? First-off, just a simple test-of-concept. Edit the JSONRPCExample.py file in the examples/jsonrpc folder that came with pyjamas. I'll locate the jsonrpc service in zope's containment root, so I change the uri in EchoServicePython from "/services/EchoService.py" to "/". That's all I need to change. Compile it using the handy "build.sh" that's in the same folder. Look in the "output" folder and see what we got. Wow. a bunch of files. JSONRPCExample.IE6.cache.html Mozilla.cache.html OldMoz.cache.html Opera.cache.html Safari.cache.html JSONRPCExample.html JSONRPCExample.nocache.html corner_dialog_bottomleft.png corner_dialog_bottomleft_black.png corner_dialog_bottomright.png corner_dialog_bottomright_black.png corner_dialog_edge.png corner_dialog_edge_black.png corner_dialog_topleft.png corner_dialog_topleft_black.png corner_dialog_topright.png corner_dialog_topright_black.png history.html pygwt.js tree_closed.gif tree_open.gif tree_white.gif I'm lazy, so instead of doing a bunch of resource or view directives in ZCML, I let my paste.ini do the handling. [app:pyjs1] use=egg:Paste#static document_root=/home/jwashin/projects/pyjamas/pyjamas-0.4/examples/jsonrpc/output then, I link that in with the composite app. [composite:Paste.Main] use = egg:Paste#urlmap / = zope /images = images /pyjs1 = pyjs1 Now, to get to JSONRPCExample.html, I need to go to http://website/pyjs1/JSONRPCExample.html But first, I need to actually handle the json-rpc requests in zope. Make a servicetest.py. Almost exactly similar to EchoService.py in the output/services folder. from zif.jsonserver.jsonrpc import MethodPublisher class Services(MethodPublisher): def echo(self, msg): return msg def reverse(self, msg): return msg[::-1] def uppercase(self, msg): return msg.upper() def lowercase(self, msg): return msg.lower() Now, a ZCML incantation. Start zope, and go to http://website/pyjs1/JSONRPCExample.html Nice page. Click the "Send to Python Service" button. Server Error or Invalid Response: ERROR 0 - Server Error or Invalid Response Damn. Pull up tcpwatch and see what we are getting. Aha. pyjamas app is sending jsonrpc with a content-type of application/x-www-form-urlencoded, so zope is not handing it off to zif.jsonserver for handling. Fix pyjamas or let zif.jsonserver handle this content-type? In zif.jsonserver's configure.zcml, in the "publisher" directive, add application/x-www-form-urlencoded to mimetypes. Restart zope. Go to http://website/pyjs1/JSONRPCExample.html It works. Change permissions in the jsonrpc:view directive. Restart zope. Go to the page. Page loads. Push the button, and I get a Basic HTTP Authentication dialog. Nice.

On Apr 5, 2008, at 6:30 PM, Alan Runyan wrote: Here is something more ZODB and less Zope related (kinda). I was talking with Benji a few weeks ago about a problem that should be easy to debug but was not. Here is the scenerio: - Customer has software on a remote machine. They are seeing unnecessary transaction commits. Just like the guy 'Analyzing a ZODB'. - Customer is completely incapable of doing anything other than putting a script on the filesystem. - Benji and I thought about it and he proposed 'the simplest thing that c/should work, monkey patch persistent.__setstate__' so that I could see what objects were being mutated. That doesn't show you which objects are being mutated. It only shows you which objects are being loaded. If you want to see what objects are actually being mutated, it would be better, IMO, to set up some sort of event channel on object invalidations. If you want to see what code is mutating objects, it would be better to set breakpoints in Connection.register. - Unfortunately ZODB 3.x does not have a Python fallback of persistent.Persistent -- its in C. The customer did not have a C compiler on their box. IIRC how I solved it was increase ZEO event log to see the oid's. Then I walked him through loading the oid up to see what object was being mutated. It was more painful than it should have been. Yup, but automating something like this might have been informative without being painful. Question: Is it possible for ZODB 3.9 to have a pure python implementation of persistent.Persistent? Probably. Maybe this would be a good ZODB GSOC project? The current C-level persistence implementation is rather nasty because of the close coupling with the persistent cache implementation. My goal is to come up with a new persistence implementation that is much simpler and more flexible with both Python and C implementations. I haven't had time to work on this though. :( If someone wanted to work on this, I'd be happy to go into more detail. ... - increasing zeo server log level and watching oid's being changed is sort-of the equivalent of turning on RDBMS logging to see SQL stmt's being executed. Unfortunately I believe without having a hook in persistent.Persistent we can never really get that level of granularity (i.e. __getattribute__ is only accessible in client) with only ZEO server logs. Regardless of whether it's implementation is in C or Python, the current implementation is complex and highly coupled. A more flexible system that I envision, would make it easier to experiment with alternate cache implementations and would also make it easier to substitute implementations that did more logging for debugging purposes. This is a transparent plea for a "new feature". But I believe it would significantly help people writing ZODB applications. Maybe people should always have a base class that you override those methods which delegate to persistent.Persistent. i.e. class MyMixin(persistent.Persistent) and mixin MyMixin instead of mixin persistent.Persistent directly? Then you can instrument the MyMixin with the logging? That would introduce lots of overhead and complexity that I don't think is warranted.

Anyway, either removing the "no-cache" header or using one that allows

a 'no-cache' header.

That is a macro call. There is no difference. It just that the macro includes the HTML needed to suck in the JS library you use. I have been working on a simple WSGI middleware filter that handles js library insertion pretty well, without complicated macros that assure that a javascript library gets included only once. It works by creating a WSGI environ variable for desired includes. Individual widgets ask a utility to register their need for a particular javascript or css resource into that environ variable.

I also am using one of the larger client frameworks available, Dojo Toolkit. The js file is around 130k if I remember. The smaller ones are great and do the job, but I wanted something larger and more widely used like Dojo to build off of. I know eventually I'll look at the JSON stuff too. Sound interesting. Hi, Greg Cool! I like the way you do the how-to. Do you plan similar how-tos for other JS libraries/techniques? Would you accept contributions? I find myself looking at mochikit (http://mochikit.com) occasionally. In its ajax-tables demo, it uses a tal(esque) syntax for dom manipulation in client javascript, which could be interesting for fans of page templates. For the future, dare I ask, maybe some zope3 stuff?

[Zope] Re: [Zope3-dev] Zope 3.1.0 RC 3 released!
In this release (and earlier 3.1 releases), there is a zdaemon test failure if you install with Python 2.4 on Unix. This is a spurious failure. The test tries to execute a script (zdaemon/tests/donothing.sh) and the installation process is making this script non-executable. We'll need to look into why the execution permissions are being cleared, or, better yet, rewrite the test to use sh to invoke the script. In the mean time, you should not be alarmed by the failure.

Downloads http://zope.org/Products/Zope3/ Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system. Changes Since 3.1.0c2 - Fixed several bugs that were considered critical. * Ported Stuart Bishop's work in ``pytz`` and ``zope.i18n`` to address broken and misleading timezone code (i.e., one issue was broken and another was misleading). * Fixed apidoc to handle extended paths, so that zope packages could be installed in software instances without apidoc losing knowledge of the core zope code. * Added custom ``executemany()`` method for cursors created through GadflyAdapter. See http://www.zope.org/Collectors/Zope3-dev/445 for discussion. - Updated ZODB to 3.5.1b2. Most Important Changes Since 3.0 - New Pluggable Authentication Utility (PAU), which is similar in philosophy to the Zope 2 PAS. The following features are available in the in the basic PAU facility: + Credentials Plugins: Basic HTTP Auth, Session + Authenticator Plugins: Principal Folder, Group Folder For a detailed description of the pluggable authentication utility, see 'zope/app/authentication/README.txt'. - Major simplifications to the component architecture: + Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication. + Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar. + Local registrations can now only have two states: active and inactive. This simplified the code so much, that 'zope.app.utility', 'zope.app.registration' and 'zope.app.site' were all merged into 'zope.app.component'. + Implemented menus as utilities. The API also supports sub-menus now. + Implemented views as adapters. Skins and layers are now simply interfaces that the request provides. - Added an integer-id facility for assigning integer identifiers to objects. - Added basic catalog and index frameworks. - Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed. - Created a new granting UI that allows advanced searching of principal sources. - Implemented a generic user preferences systsem that was designed to be easily used in TALES expressions and via Python code. Preferences can be edited via 'http://localhost:8080/++preferences++/'. A demo of the preferences can be found at:: http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the 'zcml:condition' attribute.

create a Product called whatever you like (we called ours
'GlobalModules')...
our looks like this:
in Products/GlobalModules: __init__.py
# Global module assertions for Python scripts
from Products.PythonScripts.Utility import allow_module
from AccessControl import allow_module, allow_class, allow_type
allow_module('re')

allow_type(type(re.match('x','x')))
allow_module('zipfile')
import zipfile
allow_class(zipfile.ZipFile)
allow_class(zipfile.ZipInfo)

For you, obviously, you'll want to allow_module('random'), perhaps
declare some of its own special types, etc...

[Zope] zserver blocking behavior with a slow request
Title: zserver blocking behavior with a slow request On a production Zope (2.7.6) running behind apache and connected to an Oracle database, I'm finding that once a user requests a page which runs a particularly slow sql (say up to 5 minutes), any other subsequent requests seem to take the hit as well, and return very slowly. I have 8 zserver threads and a ZODB pool size of 10. I'm fairly certain I'm not maxing these out. So is this blocking effect just expected behavior for zope? One point of note is that the requests passed from apache all bear the remote ip of 127.0.0.1. Could zserver be throttling the incoming requests due to their identical REMOTE_IP (or some other apache configuration detail)? Is there anything else I should investigate? OH btw, I am using my own connection pool and managing db interface / transactions manually, so ZSQL should not be considered a culprit. Furthermore I'm watching the connections/pool themselves and they are not maxed either. Thanks for any help.

[Zope] Puzzling Import/Export problem
A friend in Russia is still using my old ZClasses QSurvey product. He is attempting to copy an installation from one machine to another, and upgrade Zope to 2.6.4. Exporting the product and instances works fine, but some object instances will not import correctly. A product instance is a folderish object that contains other objects. One particular folderish subobject will not import correctly; all the others import fine. The .zexp of the entire product instance, with subitems, etc., imports OK, but the one folderish object shows up as "broken" in the ZMI. Exporting that object as XML and reimporting after correcting the appropriate class ID string results in a "BadPickleGet" error 7. Traceback (innermost last): Module ZPublisher.Publish, line 113, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 40, in call_object Module OFS.ObjectManager, line 561, in manage_importObject Module OFS.ObjectManager, line 578, in _importObjectFromFile Module ZODB.ExportImport, line 65, in importFile Module OFS.XMLExportImport, line 119, in importXML Module ZODB.ExportImport, line 75, in importFile Module transaction._transaction, line 368, in commit Module transaction._transaction, line 297, in savepoint Module transaction._transaction, line 294, in savepoint Module transaction._transaction, line 656, in __init__ Module ZODB.Connection, line 1034, in savepoint Module ZODB.Connection, line 470, in _commit Module ZODB.ExportImport, line 140, in _importDuringCommit BadPickleGet: 7 I have examined the xml export, and the only thing I can think of that might be a problem is that some of the object IDs for some contained items are base64-encoded and may contain Russian characters. But that does not seem to be the problem, since a similar, smaller import with only ascii characters fails with the same traceback and BadPickleGet:10. I realize that this might be an uninteresting edge-case. My backup plan is to write a script to pull the data out of the XML export and recreate the objects. Does anyone have any pointers on that? I am having trouble figuring out how that file is organized. For completeness, I am using zope-2.8.0, but this happens on 2.7.6 as well. -Jim Washington ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Searching Content Objects in Zope 3
Hello, I've been working away on an application, and it's now starting to take shape, based around a series of content objects. As recommended on this list I opted for Zope 3 to build my app, and I'm finding it quite powerful. However, I've hit a bit of a brick wall around searching. It seems from the documentation that ZCatalog is the prefered way of doing a search in Zope 2, but that this isn't implemented in Zope 3. I've got Philipp von Weitershausen's (very good!) book, and he doesn't implement a search for his recipe objects. I've also been looking at the PDF of the Zope 3 Book (which I've also found really useful) and I haven't spotted searching of objects mentioned in that. My search tool will need to take various criteria (say, number of bedrooms, maximum rent, areas the property can be located in) and scan through my objects to find all the matches. I think I can work out how to search through the objects themselves in order to find the matches, the real problem is taking in the criteria in the first place. (Although, any tips provided on the searching side of things would certainly be welcome too!) As a 'dummy run' at searching I created a View for my PropertyFolder object that shows properties based on specified criteria - I can get this to work OK, but I have to put the criteria right into the Python code, so clearly that's not acceptable... I would be grateful for anything anyone could point me to that would help me to build a tool to search my content objects. Philipp mentions the use of Utilities for searching, but beyond that, I don't know where to start. Is it possible to use Interfaces to create data entry schemas/forms for Utilities in the same way as for objects? Any help, greatly appreciated. Thanks, Jim ___ Yahoo!

Re: [Zope] Re: ZPT with Zope 3 queries - repeat over contained items
Thanks for that info. I've tried a couple of extra things (below) and if I'm reading the output right I thing you're correct about "items" returning a tuple, and "values" returning the object. When I do the repeat like this: Name The data presented look like this: (u'Property', ) However when I repeat over "values" instead of "items" like this: Name ... they change to this format: So, it looks to me like values is returning the contained item as single item, rather than a tuple of it... However, I still can't drag anything out of it. Having changed the tal:repeat to "item context/values", I have tried item/name, item/Name, item/getName, item/title, item/Title... All return "NotFoundError". I've googled, but am yet to find any Zope 3 specific documentation for ZPT - could anyone point me in the direction of some?

Re: [Zope] ZPT with Zope 3 queries - repeat over contained items
Hello, Re-reading this, I realised I'd not provided much information on the "repeat" problem, so I'm filling in some gaps. This works as I would expect: Number # i.e., if it is repeating over a property folder with four objects in it, it produces a table headed "Number" and with 4 further rows with numbers 1, 2, 3, and 4 in. However, as soon as I add any meat to it, e.g.: Number Name # Name I get an error which shows up on the error log as: "TypeError: tuple indices must be integers" I have tried the second element as all sorts: Name and: Name and: Name and: Name (all of the objects in the PropertyFolder have a "street" attribute) These all give the same error. Since my simple test case works, it seems like I'm setting the loop up correctly, but am asking for the data in the wrong way later on. getId and title certainly look from the Zope 2.6 book like they should work, and I tried the rest as "guesses". Where should I be looking to find the correct information on how to do this in Zope 3? Thanks, Jim > Hello, > > I'm building an application in Zope 3.

[Zope] ZPT with Zope 3 queries - repeat over contained items; accessing adapters
Hello,
I'm building an application in Zope 3. I have a
container object called a PropertyFolder, which holds
Property objects.
* Repeating over contained items.
I'm trying to create a view which displays a list of
all the Property objects in a property folder. I've
tried doing this as described in the ZPT chapter of
the Zope Book (2.6 edition), using a tal:repeat
statement, but I can't seem to get it working. Has
something changed in Zope 3? I've tried looking in the
Zope 3 book, but none of the references to tal:repeat
in there seem to be used for this type of thing.
* Accessing adapters in ZPT
I've created an adapter that provides a method called
getStars that can be used on Property objects. Can I
access this directly from my ZPT, as I can any other
attribute of a property object? At the moment I've got
it implemented via a Python view class, so my ZPT
accesses it like:
but other attributes can be accessed like:
so I guess I want to be able to do:
and negate the need for the Python View Class, which
only says:
def stars(self):
"""Get the stars for the property"""
rate = IPropertyRate(self.context)
stars = rate.getStars()
return stars
Thanks in advance for any tips.
Thanks,
Jim

Re: [Zope] Newbie Questions - many-many relationships? Zope 2 or 3?
Hello again, So, following the recommendations from the board I have settled on "route 3" - developing a Python Product, using Zope 3. I've been refering a lot to the Zope 3 Book (particularly chapter 13 onwards) and have progressed somewhat. I've created a "PropertyFolder" class, which can hold Property obects, and following the example in the book I've been able to make it hold *only* Property objects. My "Property" class is proving a little more difficult, however. When I've tried to make it along the same lines as the "message" class in the book, I run into difficulties - it seems to be some sort of problem with inheriting from multiple classes / interfaces. My workaround has been that I can include my __setitem__.precondition within the main IProperty interface, and make that subclass from IContainer instead of Interface. This works for me, because I'm not going to want Property objects to contain other Property objects, but I really haven't been able to track down why it should work for the message board, but not for my classes / interfaces. The errors I was getting before my work around seemed to be indicating that it wasn't a container, although I was subclassing BTreeContainer, and implementing three interfaces (one and Interface, one and IContained, and one IContainer). Mostly this presented itself as Zope complaining about using __len__ on the object. (As I say, I have worked around this, and mention it mostly in case it sheds any light on the issue below...) My current problem, however, is proving harder to work around. I want my Property objects to be able to contain Images, and sets of attributes. (A typical set of attributes would describe what is in the kitchen). I have created interfaces IAttribSet(Interface), IAttribSetContainer(IContainer) and IAttribSetKitchen(IAttribSet); and classes AttribSet (implements IAttribSet and IAttribSetContained) and AttribSetKitchen (implements IAttribSetKitchen). I am using IAttribSetContained to create a __parent__ ContainerTypesConstraint. I have wired up the kitchen attrib set in .zcml files. When I 'turn off' implementing IAttribSetContained, my kitchen attrib set is working fine, in that I can add it anywhere, and edit it. However, when I try to add a condition saying where it can go (i.e. I only want it to be within Property objects) it correctly only appears as an Add-menu item within Property objects, but on adding it, I get an error, saying "AttribSetKitchen instance has no attribute '__parent__'". My Property and PropertyFolder objects are implemented as BTreeContainers. I'm really quite stumped by this, so I would appreciate any guidance that could be provided on tracking down the source of the errors.

RE: [Zope] External editor for ZMI
I do recommend Boa Constructor, which feels the most like you're actually editing source code files (though you're editing the zope objects in place). This program has actually saved my life. Caveats: It has a few dependencies you'll need to track down, and it's a little buggy/quirky. If you're not comfortable with a bit of DIY, or you're relatively new to zope and/or python, it might be more trouble than its worth. The 'upload' mechanism in ZMI for most objects might do OK for you, then you can use whatever editing environment you want. I'm sure a lot of people have solved this particular problem for themselves in different ways, based on their own editing needs/preferences. After a little trial and error, of course.

Using the ZMI to build an application using standard objects (classes) 2. Creating new classes to use in your app through the ZMI. 3. Creating new classes to use in your app in Python. Most of the Zope Book concentrates on method 1, and the "Extending Zope" chapter is about method 2 - it mentions method 3, but says that it's beyond the scope of the book. I think I've convinced myself that the complexity of my app takes it beyond method 1, but I'm strugling to get my head around the implications of selecting method 2 or 3. Am I right in thinking that either of these will result in my building a "Product"? If I want to add extra feature to my product on the development server and then port them to the live server (with all the data on the live server being left in tact), will selection of either of these particularly help or hinder me in this? Apologies for asking so many questions, and thanks to those who have helped so far. I guess I'm just keen to start from the right place at the beginning, so save myself headaches further down the line. Thanks, Jim ___ Yahoo!

Re: [Zope] Newbie Questions - many-many relationships? Zope 2 or 3?
Thanks to those who posted suggestions - certainly gave me a few things to think about. Unfortunately I was left with one "use Zope 2", one "use Zope 3" and a "use Plone", but maybe that's just a reflection of the fact that there's more than one Zope way to skin a cat! (yeah, I know I've over-simplified the answers - no offence is meant!) On another thread (http://mail.zope.org/pipermail/zope/2005-June/159738.html), someone said: "The problem is that you develop using the ZMI. It's a bad pattern. Don't do it." but the Zope Book (2.7 version)'s chapter on Creating a Basic Application all seems to be through the ZMI. Now, Zope's original appeal to me was using the graphical interface provided by the ZMI to create a collection of objects which if you wire them up correctly will become an application, a view that I think is supported by the Zope Book. However, this view, and what I've read about Zope 3 seems to indicate that this way of doing things is deprecated. Am I correct here? Particularly, if I am building an app that I think I will want to add extra functionality to after it has been installed and is in use, is this a particular reason to avoid developing with ZMI? Say, for example that my Zope App in some way has a "House" object, which records the address, the owner, and a short description. Later on, I may wish to add further fields to record, say, the number of bedrooms, but the system is already in use - if I've developed in the ZMI, will this make it harder to make an upgrade? Now, if the answer to all of that is "yes", then I think that steers me away from the need for TTW development (TTW = Through The Web = ZMI, yes?) which steers me towards Zope 3. I'm interested by the suggestions on how to handle the relations. > Hmm, what I would start with is an attribute for a > house containing a > list of references to owners. And vice versa, each > owner has a list of > references to houses. I had thought of this, but my concern was about how to make sure that the two records are kept accurate - basically the suggestion is to keep two records saying the same thing, which just triggers alarm bells with me. Another suggestion was: > Nah. You either let every PropertyOwner have a list > of the ids of > HouseProperty objects, or the other way around. Then > you index this is > the catalog so you can search. Tada! I like the sound of this a bit better - just keep records in one place. So, if I've followed, I let the the house "knows" who owns it, and if I go to a certain owner's page and want it to give me a list of all the houses she owns, it would do a search through all the house records to see where she's mentioned. Thanks again for all the help so far - lots of food for thought.

[Zope] Newbie Questions - many-many relationships? Zope 2 or 3?
Database Question Hello, I'm a newbie, so this is a newbie question! I am currently preparing to build a web application for property lettings, and I'm very interested in what Zope has to offer. The application will need to recognise a number of different objects, such as "houses", "prospective tenants" and "property owners" (the latter of which I may implement as user types, which would allow these people to log in and amend some of their own information.) I'm very interested in the Object Oriented way of doing things; for example, I'm thinking about implementing houses as a folder-ish object, so it would be able to contain photos of the house in question. The biggest stumbling block I am facing is how to do something "Relational" in an OO environment. Specifically, I've been scratching my head for a while about how to handle a many-many relationship: a property owner may own more than one house; conversely, a house may have more than one co-owner - consequently it's not appropriate to have either containing the other. I've googled for general information about handling many-many relationships in OO, and most of what I've come across has only indicated that it can be tricky! Having a look through past threads on this mailing list I've noticed a few references to mxmRelations (http://www.zope.org/Members/maxm/products/mxmRelations) which seems to match up - have I got the right end of the stick? Before I jump in with this I'd appreciate any advice or guidance you could provide - it'd be greatly appreciated. While I?m on, I?ve noticed that Zope 3 has been released. Is this now the recommended development environment, or am I better off sticking with Zope 2 for now, and porting my application once Zope 3 is a bit further down the line? I?d greatly appreciate any guidance that can be provided on these subjects. Thanks in advance, Jim ___ Yahoo!

RE: [Zope] python question
sort() on a sequence does not return anything. It operates on the
[mutable] sequence in place.
You probably want to push this bit into a python script where you have
more elbow room, and do this:
files.sort(etc,etc)
return files[0]

[Zope] the joy of hacking ZPublisher
Title: the joy of hacking ZPublisher In my Zope 2.7 Product, I'm trying to implement a special folder, which intercepts the publishing call to any subobject and wraps the entire call in another. A concrete example: where the default action would be to traverse /MyProduct/SpecialFolder/something, and publish the attr 'something' from SpecialFolder, I want this to happen instead: doSomethingBeforeCallingTheRequestedObj() try: return mapply( something, blahblah...) finally: doSomethingAfterCallingTheRequestedObj() Why? I need to do stuff to the REQUEST before the object is called (this part wasn't difficult), and then do something *after* it's called - no matter what the results were. But only for publishables that live in or beneath the Special Folder. In fact I have something working, but one big problem - it breaks management screens in a bad way. The implementation is pasted below. Is there some much simpler way to accomplish this behavior? And am I short-circuiting security machinery in some dangerous way? class Wrapper(Implicit): """voodoo""" id = meta_type = title = "Wrapper" def __init__(self, publishable): self.pub = publishable def index_html(self): """ render the results to the client """ REQUEST = self.REQUEST print self.__class__.__name__, 'calling', self.pub try: return mapply(self.pub, REQUEST.args, REQUEST, call_object,1, missing_name, dont_publish_class, REQUEST, bind=1) finally: print self.__class__.__name__, 'done' print '' print '' __call__ = index_html Globals.InitializeClass(Wrapper) class SpecialFolder(Folder): def __bobo_traverse__ (self,REQUEST,key): print '__bobo_traverse__', REQUEST.URL, key stack = REQUEST['TraversalRequestNameStack'] target = getattr(self,key) if stack: return target return Wrapper(target).__of__(self) ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

RE: [Zope] high loads, more threads, spinning wheels
Can this be taken to mean that:
- the practical maximum number of threads to run your single (non-ZEO)
zope instance is {number of zodb connections in pool} else you risk
deadlock
if yes, would upping the number of ZODB connections effectively raise
the ceiling - e.g. 12 ZODB connections -> 12 threads should perform
properly ? Is increasing the number of ZODB cx's possible, let alone
advisable? (why the default of 7 - not 6 or 8?)
More concretely, is there any good way to increase the request-handling
capacity of a standalone instance, beyond the limits imposed by the
defaults, without deploying ZEO?

Doing runzope or zopectl with -M aren't working, and there is no obvious directive in zope.conf for it.

It's mainly useful for changes that are straightforward to recover from. We have to balance lots of different factors taking into account *everybodies* interests, the best we can *together*. Jim Andrew Milton wrote: I think people on this list need to realize that eventually, the direction of any significantly large Open Source project is hijacked by the relatively small number of people actually doing the work. The reasons for this are many-fold, but, normally come down to a lack of communication between the developers and the users, which is realized in a lack of understanding by the developers of what the users want. This for the most part isn't generally a problem, until, the developers start to do things "for the user's own good", like remove features that are "kludgey", or a "hack", or , which generally means either noone wants to work on it, or some other change caused it to break, and noone wants to fix it. Now to the credit of the Zope guys, they actually poll the users to find out, rather than just announce the demise of something. However, in general once you add a feature, you can be guaranteed, that somewhere, someone is using it, so removing it will always cause a problem. So there will always be an uproar when you poll. You're never going to be able to reduce the feature set between point releases without upsetting some group of people. So why don't we stop all this nonsense now, and just agree, that you're never going to do that d8) You have Zope 3 to remove all the stuff you hate d8) In my opinion if you change something, it's your responsibility to fix the resulting breakage. That's part of your responsibiliity to the rest of the community (i.e. the [mostly non-paying] customers). If you don't think you have this responsibility to us, then you should work on your own version of Zope, where you're not impacting anyone else.

Which is extremely valuable. If that's not enough... fine... drop ZClasses, then DTML (you know, its next)... and all the folks in this boat with me. (There are no plans to deprecate DTML. It is even supported in Zope 3.) ZC should decide whether the benefits of ZClasses for low-end developers match against the hurdles to keeping it with the newer Zope releases. If they don't see a need for this skill-level type of tool in Zope's feature list, they will pay down the road... Growth is king, even for Zope, who grew this platform? Growth means newbies, right? What elements got Zope to where it is? Could ZClasses be on that list? Why? Vey well said. I think this is, but should not be underestimated. This is something I think about a lot. I think Zope needs to support developers and non developers. Zope 2 was weak in supporting developers. Over the years, new techniques and technologies have evolved to make Zope development better for proffessional developers, but we still need the non-developers. And seeing comments like... - "Move to Zope Python Products" - you cant see the skill differences between OOP & Zope's API vs. ZClasses - "Use the Archetypes/CMF/Plone setup" - UML training? the CMF API and Plone underpinnings, easy? - "Maintain it yourself then" - Update very slick code within Zope's flexible and aging API, with ZODB API too? Maintain it...Yeah sure, hows this afternoon. ... just show me how under-represented that beginner and intermediate Zope developers use this list... and then I think, perhaps there aren't any, just me and a few others... and if that's the case, Zope's screwed, and the horse I rode in on. :) This list is for you. While you shouldn't have to maintain Zope yourself, you *do* need to be vocal about what you want. (Of course, at some point, work needs to get paid for. If someone wants a new feature that the developers don't want to develop out of the goodness of their hearts or even an old feature that no one wants to maintain, someone may have to be willing to fund some development. I'm not asking for this in this case.) And so here's the confession... "Hello, I'm Jon... I've used Zope for 2 years, and I can't help others program high-level Python OOP tools/platform resources in a propriety web content management server. I only can support their efforts when the occasional mailing list opportunities present themselves." And that support is greatly appreciated!

You listed out the reasons why someone wouldn't want to use them going forward, but what are the reasons why not to support them as legacy into 3/2.10? Are you saying you want them in 2.10 but not necessarily beyond that (e.g. 2.11)? Or that you don't see why we don't support them indefinately? It takes effort to support old features. We have to weigh the benefits against the cost of the feature. For example, Zope 2.8 has been delayed substantially due to the effort to keep them going.

[Zope] Does anyone care whether we deprecate ZClasses?
ZClasses are a feature that support through-the-web development. Many people have found them useful in the past, but they have some significant deficiencies, including: - They can't be managed with file-system tools, especially revision control systems like CVS and subversion. - They don't work well with Python development tools, like profilers and debugger. - They aren't being actively maintained. Most serious Zope developers stopped using them a long time ago and are frustrated that we still expend resources keeping them around. For example, the release of Zope 2.8 has been delayed by the requirement of getting ZClasses working with Zope 2.8. We could choose to deprecate ZClasses. If we deprecated them in Zope 2.8, they would still work in Zope 2.8 and Zope 2.9, but their support would be removed in Zope 2.10. Would anyone be upset if this happened?

Re: [Zope] porting from Python Methods to PythonScripts in2.3.0;LoginManager too
The text of an external method for converting Python Methods to Python
Scripts was posted to the list a while back. I forget who because I
just copied and pasted at the time. Anyway, credit to whoever, and
apologies for not having the name.
I took that and made something that works for me as a Python Script.
(Though my Methods have been rather simple...)
Standard caveats, YMMV, etc, but it does a quick pass on the Methods in
the folder where it is and makes Scripts from them when you hit the
'test' tab, saving the old ones as methodname.old. It's not perfect
(e.g., it will import random if you use whrandom); it's just a bit
easier than manually editing (copy, paste, edit) for the same
functionality. It would be pretty easy to recurse all folders and
change them all, but I am not that bold yet. It seems debugged enough
to post. I am sure someone will let me know if otherwise.

I would put the Python Script in the ZClass's /methods and see what happens. -- Jim ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] ZClasses meet PythonScripts, sample request
Hi, Tim
What is the name of the propertysheet in your ZClass that these values
are on? Is it 'job_info'?
Where is the editFormAction Python Script? It should be in your ZClass's
/methods. If you are instead acquiring it from a Folder somewhere, you
will need to use 'context' instead of 'container' inside the Python
Script.

Re: [Zope] ZClasses meet PythonScripts, sample request
Hi, Tim I have it. The Python Script I sent you: container.propertysheets['job_info'].manage_changeProperties(REQUEST) needs to be rewritten: container.propertysheets.job_info.manage_changeProperties(REQUEST) Perhaps someone could explain why the first does not work. One point about your form: You have id as a form variable. You will be disappointed by its behavior.
